Need for Speed: Nitro-X is a newer installment and the sequel to the original Need for Speed: Nitro. Announced shortly after E3 2010, EA released details on bringing the Need for Speed series onto Nintendo's digital distribution DSiWare service and the upcoming Nintendo 3DS system. Titled Need for Speed: Nitro-X, the game is essentially the original release with a couple of updates, such as 18 licensed vehicles, 6 never-before-driven police units for use in Super Pursuit Mode, custom tags for in-game usage of the DSi camera, 16 updated tracks from all six original Nitro locations, a revised career mode, local multiplayer matchs for up to 4 players, as well as new rewards and unlockables. The game was released as a digital download only and is priced at a premium of 800 Nintendo points. It was originally going to be released on September 20, 2010, but EA delayed the game slightly to work on improving the in-game physics engine. It then became rescheduled for a release on October 8, 2010 in North America, but it was delayed once again and was released on November 15, 2010 in North America and November 26, 2010 in Europe.
